Okay, so i just bought a gaming computer off of ebay. It has been working fine with the new speakers i bought. But just today the computer acted up and i had to reset the BIOS to default. Now when i play a video on full volume, it comes out fairly distorted through the left speaker and about 25% volume. Ive tried both the front and back port, and will a different pair of speakers. Ive figured its the computer or motherboard because i can plug the speakers into my phone and they work perfectly fine.

If it helps, the speakers are These

I uninstalled all drivers and reinstalled them. Now there isnt even sound when playing a video, just a constant high pitched sound

Well I did the little test sound, right? and it comes out at maybe 40% through the left speaker and not at all through the right speaker. and there is still a high pitched constant noise
